Abstract
A sealing arrangement for sealing a machine element, preferably a shaft, with a sealing ring and leak-detection means that comprises a sensor for detecting the leak, and a depot for picking up the leak. The depot is monitored by the sensor and the depot consists of an absorbent and/or swellable material, and is arranged so as to permit delayed leak detection by the sensor.
